It has been found that one hanger such as a hook 17 and clamp 18 is sucient to support the modified form of fitting a tub although it is obvious that additional hang-` ers may be employed if desired;

A further modified form or application of this invention rests in the use of a perforated plate, which may be placed on the Hoor or bottom inside the tub, under which the aerator in the jet form may be installed. The purpose of such an installation is to permit of the perforated plate acting as sort of distributor or deflector for the currents of aeration permitting of more even distribution throughout the entire expanse or area of the plate, depending upon the a1"- rangement of perforations and/or the type of jet employed. In Figs. 5 and 6 there is shown an example of this modification comprising a conventional tub or bath 1b provided with an aerator substantially like that heretofore described with the exception of the former of which the manner of delivery to the tub., In this form the tube 16 is continued to the bottom of the bath and caused to discharge through a Y discharge fitting 6b, generally similar to casing 6, under a perforated pan 23. Pan 23 extends over the bottom of the tub and is spaced therefrom by a flanged rim 24. 5.

The operation of all modifications is identical and believed to he apparentfrom the foregoing description and therefore need only be briefly summarized. VA. 'supply of water entering the elbow 3 from any suitable supply or source will pass through tube 2 and through the nozzles 11 and 12. As the water emerges from nozzles 11 and l2 and is al- `lowed to expand, a partial vacuum or suction 1s created which will draw air in through apertures 17. The air taken in will pass through the annular passage between tubes 2 and 16 and into the discharge tubes 13 and 14 or the tube 21 as the case may be; Tubes 13 and 14 or tube 21 will therefore discharge a mixture of air and water which will create a thorough agitation and uniform movement throughout the tub and also aerate the water in the tub. This movement and agitation is due both to the movement of the incoming water and to the entrapped airin the water,

through the water in the tub.

It is obvious that many changes may be made in the details departing from the spirit and scope of this invention as defined in the claims appended hereto. For example, a double jetted aerator may be used in order to accomplish better distribution, thus the conduit 2 in the aerator 1.
